Ziziphi iingcebiso eziphambili zokuthenga ii-AC alternators ezilungileyo

Okwangoku, ukunqongophala kombane kwihlabathi kuya kusiba mbi ngakumbi.Iinkampani ezininzi kunye nabantu ngabanye bakhetha ukuthenga iiseti zejeneretha ukunciphisa izithintelo kwimveliso kunye nobomi obubangelwa kukungabikho kwamandla.I-AC alternator yenye yecandelo elibalulekileyo kwiseti yejenereyitha epheleleyo.Indlela yokukhetha ii-alternators ezithembekileyo, ezi ngcebiso zilandelayo kufuneka ziqatshelwe:

I. Iimpawu zoMbane:

1. Inkqubo ye-excitation: Ngeli nqanaba, inkqubo yokuvuselela i-alternator ye-AC yezinga eliphezulu i-self-excitation, ngokuqhelekileyo ixhotyiswe nge-automatic voltage regulator (AVR).Amandla okukhutshwa kwe-rotor ye-exciter idluliselwa kwi-rotor yomkhosi ngokusebenzisa i-rectifier.Izinga lohlengahlengiso lwe-voltage ezinzileyo ye-AVR ubukhulu becala ≤1%.Phakathi kwazo, i-AVR ekumgangatho ophezulu inemisebenzi emininzi efana nokusebenza ngokuhambelanayo, ukukhuselwa kwamaza aphantsi, kunye nohlengahlengiso lwangaphandle lombane.

2. I-Insulation kunye ne-varnishing: Ibakala lokugquma kwee-alternators ezisemgangathweni ngokuqhelekileyo liklasi "H", kwaye zonke iindawo zalo ezijikelezayo zenziwe ngezinto eziphuhliswe ngokukodwa kwaye zifakwe kwinkqubo ekhethekileyo.I-alternator iqhuba kwiindawo ezinzima ukubonelela ngokhuseleko.

3. Umoya kunye nokusebenza kombane: I-stator ye-alternator ephezulu iya kuhlanjululwa ngamacwecwe ensimbi epholileyo kunye ne-magnetic permeability ephezulu, i-wind-stacked windings, isakhiwo esinamandla kunye nokusebenza kakuhle kwe-insulation.

4. Ukuphazamiseka kwefowuni: I-THF (njengoko ichazwe yi-BS EN 600 34-1) ingaphantsi kwe-2%.I-TIF (njengoko ichazwa yi-NEMA MG1-22) ingaphantsi kwama-50

5. Ukuphazamiseka kweRadio: Izixhobo eziphezulu ze-brushless kunye ne-AVR ziya kuqinisekisa ukuba kukho ukuphazamiseka okuncinci ngexesha lokusasazwa kwerediyo.Ukuba kuyimfuneko, isixhobo esongezelelweyo se-RFI sokunciphisa sinokufakwa.

II.Iimpawu zoomatshini:

Umgangatho wokhuseleko: Iindidi ezisemgangathweni zazo zonke iijenereyitha zomhlaba ze-AC yi-IP21, IP22 kunye ne-IP23 (NEMA1).Ukuba kukho imfuneko yokhuseleko ephezulu, ungakhetha ukunyusa umgangatho wokhuseleko we-IP23.Uhlobo olusemgangathweni lwejenereyitha ye-AC yaselwandle yi-IP23, IP44, IP54.Ukuba ufuna ukuphucula umgangatho wokukhusela, njengokusingqongileyo kunxweme lolwandle, unokuxhobisa i-generator ye-AC kunye nezinye izixhobo, ezifana nezifudumezi zendawo, izihlungi zomoya, njl.

Ukunqongophala kwamandla ehlabathi kukunyuse kakhulu ukuthengiswa kwe-AC alternator/ jenereyitha.Amaxabiso ezincedisi ze-AC generator ezifana ne-disc couplings kunye ne-rotors zinyukile kwibhodi yonke.Unikezelo luqinile.Ukuba ufuna umbane, ungathenga iijenereyitha ze-AC ngokukhawuleza.Ixabiso lejeneretha ze-AC likwanyuka rhoqo!
